Definitions

  • the present invention relates to a coupling for connecting and / or holding together two parts, in particular for a bicycle trailer, with the features of the preamble of claim 1.
  • Bicycle trailers are becoming increasingly popular.
  • One of the reasons for this is that the possibilities for using bicycle trailers are constantly expanding.
  • There are multifunctional children's bicycle trailers which, in addition to trailer operation, also offer the option of using the bicycle trailer as a stroller or as a so-called jogger by simply converting it.
  • a front wheel is attached to the chassis of the bicycle trailer for the respective function and the drawbar of the bicycle trailer is removed or folded away.
  • Various parts must therefore be connected to or removed from the bicycle trailer.
  • the bicycle trailer must be regularly coupled to or uncoupled from a bicycle or pedelec for use as a bicycle trailer.
  • a trailer hitch with two cooperating and detachable coupling parts known, one of which is fixedly connected to the vehicle and the other is connected to the drawbar.
  • One of the coupling parts is a coupling bolt with a circumferential groove and the other is a bushing that encompasses the coupling bolt.
  • a locking pin can be inserted and secured in a guide in the socket in such a way that the locking pin engages in the circumferential locking groove of the coupling bolt inserted into the socket and thus secures the coupling bolt against slipping axially out of the socket.
  • the WO 2013/15678 known to provide spring clips instead of a locking pin, which engage in the locking groove of the coupling pin after the socket has been plugged onto the coupling pin. To release the socket from the coupling bolt, the spring clips can be pressed out of the locking groove as an unlocking means using a push button, so that the coupling bolt is free again and can be removed from the socket. Finally from the WO 2013/15678 also known as a lock for blocking the unlocking means or as theft protection.
  • a generic coupling for connecting a motorcycle to a sidecar is known.
  • a partially round spring is designed as an insert piece on one side of the coupling, which is inserted from the side into a tongue groove on the counterpart of the coupling.
  • a locking shaft is provided which blocks the semicircular spring from shifting in the spring groove in the locked state.
  • the locking shaft is rotatably mounted and has an unlocking section which does not engage in the spring in the corresponding rotational position of the locking shaft and a locking section which engages in the spring in the corresponding rotational position of the locking shaft and there interacts with a recess on the spring to lock it.
  • the disadvantage here is that the coupling connection is quite stiff and can only absorb forces and moments to a very limited extent.
  • document GB 27361 discloses the preamble of claim 1.
  • an object of the present invention is to provide a structurally simple coupling that is easy to handle. This object is achieved with a coupling of the type mentioned at the beginning with the features of claim 1.
  • An essential core of the present invention consists in the locking shaft mounted in the second coupling part, which is designed and mounted in such a way that its locking section engages in the locking groove of the first coupling part and can thus lock the first coupling part and the second coupling part, and that the locking shaft can lock the locking groove and so that the first coupling part can be released again by a simple rotation, in that the locking section is rotated out of the locking groove.
  • a locking shaft With such a locking shaft, an extremely compact and robust construction of the coupling is possible. In principle, it does not matter whether the locking groove is formed on the insert and the locking shaft is coupled to the sleeve, or whether the locking groove is formed in the sleeve and the locking shaft is provided on the insert, the latter embodiment being structurally possible but significantly more complex .
  • an essential advantage of the invention is that the forces required to connect the coupling parts are comparatively very low, and a secure connection is nevertheless ensured.
  • the coupling according to the invention can be used for a large number of connections. So the coupling according to the invention can simultaneously take on a joint function, in particular when the insert has a round cross-section and is rotatably mounted in the sleeve.
  • the coupling according to the invention can be used as a trailer coupling for bicycle trailers to attach the drawbar of a bicycle trailer to a bicycle, one of the two coupling parts being fixed to the bicycle and the other of the two coupling parts being formed at one end of the drawbar.
  • the coupling can also be used to connect a suspension for a buggy wheel to the frame of a bicycle trailer, the suspension of the buggy wheel then being freely rotatable about a substantially vertical axis.
  • the coupling has no degree of freedom and, in particular, is not designed as a joint.
  • the insert can also have a non-round, for example oval or polygonal, cross-section which interacts with a corresponding hollow cross-section of the sleeve so that the two coupling parts cannot move relative to one another when they are locked.
  • means can also be provided which, in the locked state, block all possible degrees of freedom of the coupling parts.
  • Such a coupling according to the invention is suitable, for example, for releasably connecting or securing the drawbar on the bicycle trailer, the first coupling part being formed on one end of the drawbar and the second coupling part on the frame of the bicycle trailer.
  • the locking shaft of the coupling according to the invention has an axis of rotation which is arranged essentially transversely to a direction of insertion of the insert into the sleeve, preferably parallel to the locking groove. This has the essential advantage that the locking section of the locking shaft can be pushed to the side when it is inserted through the insert.
  • the coupling according to the invention can be made even more compact if the axis of rotation of the locking shaft runs through a section of the locking groove, the unlocking section having a negative radial extension with respect to the axis of rotation, so that the axis of rotation of the shaft runs through the recess.
  • the axis of rotation of the locking shaft does not have to be guided completely past the first coupling part, but can be positioned closer to the first coupling part.
  • a spring in particular a torsion spring, acting on the locking shaft is provided as a means for rotating the locking shaft into the locking position. So it is possible that the The locking section of the locking shaft is deflected when the insert piece is inserted into the sleeve by the insert piece against a spring force and is then automatically screwed into the locking groove of the insert piece by the tensioned spring as soon as the insert piece is inserted far enough into the sleeve. This ensures extremely simple coupling of the two coupling parts.
  • crank or a lever with which the locking shaft can be rotated manually, can also be provided as the means for rotating the locking shaft into the locking position.
  • a stop element which interacts with a stop element on the second coupling part, can preferably be provided on the locking shaft as the means for holding the locking section in the locking position.
  • the stop element counteracts any turning out of the locking section from the locking groove caused by a possible pulling out of the insert, so that the first coupling part and the second coupling part, when they are locked to one another, can no longer be easily released from one another.
  • the locking shaft is held in the locking position by the stop elements against a spring force, so that it is avoided that the locking element can move within the locking groove, for example due to vibrations, or is even accidentally released from it.
  • the spring used for this can be the same spring that is used as the means for rotating the locking shaft into the locking position. It must then be pretensioned accordingly.
  • locking section can also be used, such as, for example, latching means or grippers which hold the locking shaft when it is in the locking position. It is also possible to provide holding means which hold a lever or a crank for manual rotation of the locking shaft as soon as the shaft is in its locking position.
  • the locking shaft in a preferred embodiment according to the invention it can have at least one unlocking segment with a stop surface provided on the outside of the locking shaft, which interacts with a trigger for releasing the locking shaft from the locking position.
  • the trigger can, for example, be an automatic actuator, for example a lever, which is tensioned and locked against a spring force when the insert is inserted into the sleeve, when the locking shaft is in its locking position and can be manually unlocked, the lever then acting on the stop surface and rotating the locking shaft from its locking position to an unlocked position.
  • the stop surface of the unlocking segment which is provided as a means for releasing the locking shaft from its locking position, can also be used as a stop element for holding the locking shaft in its locking position, namely when the trigger is so fixed in an initial position that the locking shaft is in its locking position with the stop surface rests against the trigger.
  • the release in addition to the release function, the release also has a holding function as a stop element of the second coupling part.
  • the stop surface of the unlocking segment is preferably located in a plane that intersects the axis of rotation of the locking shaft, so that the forces applied by a trigger act on the shaft in the circumferential direction.
  • the unlocking segment has a recess with a smaller radial extent than the outer radius of the locking section in an area lying in front of the stop surface in the actuating direction of the trigger.
  • a manual actuator is preferably provided as the means for releasing the locking section from the locking position.
  • the manual actuator preferably interacts as a trigger with the stop surface of the unlocking section of the locking shaft.
  • a spring-loaded pushbutton acting on the locking shaft is provided as a means for releasing the locking section from its locking position.
  • the direction of movement of the push button in almost every direction, in particular in the direction of insertion of the insert into the sleeve, but also transversely thereto, without any particular structural effort being associated with it.
  • a stop element formed on the push button on a corresponding one Act on the locking shaft. If the direction of actuation of the push button is parallel to the shaft, the active surfaces of the stops can be inclined so that the stop on the shaft side is pushed to the side when the push button is actuated and the locking shaft is thus rotated in the desired direction. If the direction of actuation of the push button is transverse to the axis of rotation of the shaft, the interacting stop surfaces on the shaft and push button preferably run transversely to the direction of actuation.
  • the stop formed on the manual actuator is the stop element formed on the sleeve on the second coupling part for holding the locking section in the locking position.
  • the stop formed on the manual actuator thus has a double function, namely that of holding and releasing the locking section from its locking position.
  • a pinion gear can also be considered as a further means for holding the locking shaft in and / or releasing the locking shaft from its locking position.
  • a manual actuator such as a push button or an automatic trigger such as a motor can be provided with a rack that interacts either directly or indirectly via an intermediate pinion with a pinion arranged on the shaft.
  • the coupling has a lock which is designed to be able to prevent unauthorized release of the locking section from the locking position.
  • the lock can, for example, be designed in such a way that it can act on the locking shaft and block it in the locked state.
  • the lock is preferably designed to be able to block actuation of the manual actuator.

  • the coupling according to the invention makes it possible to connect a large number of attachments of the bicycle trailer to a bicycle trailer by simply plugging or plugging one coupling part onto or into the other coupling part, and, if a push button is provided in each case, to detach them from the bicycle trailer by pressing the push button .
  • This makes the conversion of the bicycle trailer extremely easy, as each coupling follows a uniform, simple operating concept. In this way, incorrect handling by the user can be largely avoided.
  • the basic construction of the invention with a locking shaft which can lock the coupling by simply rotating it into a locking groove on the insert or in the area of the sleeve, offers a large number of design variations. If a manual actuator is used to release the coupling, it can optionally be arranged so that its actuation direction runs in the longitudinal direction of the insert or at right angles to it.

  • the coupling has only one degree of freedom. In this way, the coupling pin 101 can rotate freely within the sleeve 89.
  • the push button 151 in the coupling housing 152 is aligned with the coupling bolt 152, so that its stop pins 154, 155 are moved parallel to the longitudinal axis of the coupling bolt 152.
  • the lock cylinder 156 is arranged in the coupling housing 152 next to the push button 151.
  • the arrangement of push button and lock cylinder shown corresponds essentially to the arrangement in FIG Figures 1 to 8 illustrated embodiment, with the only difference that the locking shaft 157 differs from the embodiment of Figures 1 to 8 in relation to the coupling bolt is not arranged on the side of the lock cylinder, but on the side of the coupling bolt opposite the lock cylinder, and the stop pins 154, 155 are therefore arranged differently on the push button 151.
  • the basic arrangement of the Figures 16a and b differs from that of the Figures 15a and b in particular in that both the push button 161 and the lock cylinder 162 are arranged in the coupling housing 163 in alignment with the coupling bolt 164 to be inserted therein, the lock cylinder 162 being supported in the push button 161 and surrounded by it in a ring.
  • the bolt 61 arranged at the bottom of the lock cylinder to lock the push button 161 interacts with a shoulder piece formed in the coupling housing.
  • the push button 171 is arranged transversely to the longitudinal axis of the coupling bolt 172.
  • the lock cylinder 173 lies between the push button 171 and the coupling bolt 172, also transversely to the actuation direction of the push button 171.
  • the arrangement of the push button 171 transversely to the longitudinal axis of the coupling bolt 172 causes hardly any changes, if at all, in the design of the locking shaft 174 of the selected length of the pins 175, 176 of the push button 171, it is only necessary to adapt the position of the stop surfaces of the locking shaft for the pins of the push button in relation to the position of the unlocking section of the locking shaft.
  • a downwardly projecting locking element 177 is provided laterally on the underside of the lock cylinder 172 and can be aligned by the lock cylinder 172 longitudinally or transversely to the direction of movement of the push button 171. If the locking element 177 is perpendicular to the direction of movement of the pushbutton, it rests against a nose 178 arranged on the underside of the pushbutton and thus locks the pushbutton.
  • a lock cylinder can be dispensed with if anti-theft protection is not required. If a locking cylinder is used, it can be arranged in any variant transversely to the push button, optionally between the push button and the coupling bolt (insert), or also essentially to the side of the push button.
  • the possible variations in the construction of a coupling according to the invention are not limited to the exemplary embodiments shown and described in the figures.
  • the insert pieces of the coupling do not have to have a circular cross-section and can also be angular or non-circular, in particular when no degree of freedom is required in the coupling.
